From bb05e4ba452ada7966fbced4e829aa029f546445 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Tue, 15 Nov 2011 12:57:03 +0000 Subject: [PATCH] efi.h: Add allocation types for boottime->allocate_pages() Add the allocation types detailed in section 6.2 - "AllocatePages()" of the UEFI 2.3 specification. These definitions will be used by the x86 EFI boot stub which needs to allocate memory during boot.
